- To all whom it may concern:

-Be it known that I, ALVA D. Lsn a citizen of the United States of America, and a resident of Brookline,-in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Oil- Burners, of which the following is a specification. r

This invention relates to apparatus for burning O'Il has for its object the production of a device in which oil under pressure may be usedas a combustible and in 'which superheated compressed air and superheated steam may be mixed ivith the oilat its point of ignition.

It has for a further-object the production of a device whereby the oil, superheated compressed air, and superheated steam may be mixed in any desired quantities.

The invention consists in certain novel features o construction and arrangement of parts which will be readil understood by reference to the description of. the drawings and to the claims hereinafter given.

2 5 Of the drawings: Figure 1 represents a vertical section of an apparatus embodying the features ofthis invention. Fig. 2 represents a horizontal section of the same on line 2-2 on F ig. 1. Figs. 3 and 4 represent end views of a burner utilized in the apparatus. Fig. 5 represents 'a longitudinal vertical section of the same, and Figs. 6, 7, and 8 represent transverse sections of the same on lines 6-43, 7-7, and 88, respectively.

- Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 represents a suitable wall of fire brick or similar material the interior chamber of which forms a suitable fire'pot 11 provided with the usual door'l2 communicating therewith. Above the fire pot 11 is .a boiler 13 provided with a. phi' rality of pipes 14 for'the passage of heat therethrough to the stack 15. l1rom -"the steam chamber ,16 of the boiler 13 extends a 'pipe'17 provided with a suitable valve 18 which communicates with a coil 19 surrounding the fire-pot 1-1 and embedded in thema- This coil is situated sufiiciently near to the interior of the walls 10 to cause the steam passing through said coil to be subjected to the heat contained within the fire-pot while said coiled pipe 19 is protected from direct contact. with the flame. I

The opposite end of the coil 19 communicates, by means of a pipe 20, with theannular passage 21'surrounding the exterior of the wall 10. Vertical pipes22 form a means of communication between said" pi es 21 and the interior of a-casing 23extend1ng radially through the wall 10 into the.interior of the fire-pot 11. From each of the casings 23 extends a pipe 24 communicating with the interior of anannular pipe 25 surrounding the exterior wall 10 of the fire-pot 11 and communicating by means of the p1 e 26 with the coil '27 embedded in the material of said wall 10 in a similar manner to the coil 19 so thatthe material passing through the coil will be subjected to the heat in the fire-pot but the pipe itself will not conle into direct contact with the flame. The opposite end of the coil 527 communicates by means of a pipe 28 with a tank of com ressedair 29, said pipe being provided wi lr-a suitable. valve 30. The tank 29 is connected by means of a pipe 31. avith'a suitable air compressor 32 which may he of any well-knowncon struction. Vvhen thisair comprcssmf iso eratcd by means of the pulley 2:33 air will e compressed and forced through the pipe 31 into the tank 29 from which it may be drawn through the pipe 28 iuto'the coil 27 where it becomes superheated and passes therefrom through the pipe 26 into the annular passage 25 communicating by a plurality of downwardly. extending pipes 24 withrach of the casings 23. Each of. the casings 23 is also connected by a pipe 34 with an annular pipe 35 surrounding the fire-pot 11, said pipe 35 communicating by means of the pipe 36 with the (lisclnirge outlet 37,01? a suitable pump 38 driven by the pulley/39 and connected by means of the pipe 4.0 with, an oil tank 41. When the pump 38 is operated by means of the pulley 3.) oil is forced under pressure through the pump 25$ and through the pipe 36, annular pipe 35 and downwardly extending pipes 34 into the interior of the casing members The interior of the casing 23 has threaded thereto a tubular member 42 adjustable end- Wise therein by means of the milled head 43 and threaded to the interior of the member s2 is another tubular member/t4; adjustable therein by means of the milled head {53.

The exteriorly threaded portion of the member co-aeting with the threads in the interior of the casing 33 extends between the inlet pipe 34 and the outer end of the-casing member and thereby prevents any oil whieh enters the chamber $6 in the easing 23 "from passing outwardly and insuring its passing through the annular passage 47 to the outlet aperture 48 in its tapered inner end 49 The threaded portion. of the member 42 is cut away in the plane of the inlet pipe 22 thereby forming a shallow circumferential groove 22*; communicating with said inlet pipe 22, and through the ports 50 with the interior of said pipe 42. In a similar manner the exteriorly threaded portion of the tubular member 44 -co acting with the interiorly: threaded portion of the tubuluar member 42 extends from the pipe 2210 the outer end of said member thereby preventing the steam which enters through the inlet pipe22 into,

1 the interior of the casing 23 and through the ports 50 in the tubular member 42 from'passing outwardly either, between thdcasing member and thetubular member 42 or outwardly between thetwo tubular members 42 "and 44 and oblige it to pass through the annular passage 51 to the outlet aperture a2 in the tapered end 53 thereof. In like mannor a portion ofthe exterior threads on the tubular member 42 and the exterior-threads on the interior tubular member 4% are cut away in the plane of the air inlet pipe Zl thereby providing an exterior annular p'assage in each of these tubular members the passage 54 of which communicates through ports 56 cut through the exterior tubular member 42 with the interior annular passage 55 which in turn communicates through ortsfi'? cut through the'inner tubular memer 44 with the interior chamber 58 of said inner tubular member 14. 1

The superheated com ressed air entering through the pipe 24 W11 pass through the annular passages 54, orts 56 annular passage 55, and ports 57 into the interior chain.

ber 58 of the inner tubular member Minn?! pass along said interior chamber 58 to the outlet aperture 59 in the tapered end 60 thereof.

The walls of the tapered ends 49, 5 3, and. {30 are all arallelwith one another and it.

s. obvious t at any-longitudinal adjustment of the tubular members will narrow or widen the annular passage between said walls to regulate the outlet aof the oil through the passage 47 or steam throu h the passage 5L In a similar 1nanner t e discharge of so erheated compressed air may be regulate by means of the tapered end 61 of a valve 62 threaded at 63 'to the interior tubular member l t'and operated by means/of the milled head (it to regulate the discharge of superheated air through the outlet aperture 59. i Y

The apertures 48, 52, and 59 are all in anial alinement and the outer walls thereof are flaring being substantially parallel with the inner walls of a conical member 65 supported by the s ider arms 66 forming a part of the annu ar ring 67 threaded at )8 to the exterior of the casing 23 and provided with gear teeth 9. The oconical end 65 is so situated relative to the a-nn-ular discharge passage between the tapered ends of the various adjustable tubular members that the oil,-- steam, and air being dischar d' intensity of the flame'may bcn'egulated'toa- 'nice'ty. 11i orderfo act-omplish this resultthe annular ring 673s mounted in .a chain'- her with-in the' wall"1O so that'th'e gear teet-h and' the threads ;upon the exterior ofqth'e easing nember QZlW'vill. not besubjected-to the intense heat within the fire-pot; Within t-liiseliamber 70 the g ar 69 is proy'ided "with a dri'i'ing pinion 71 mounted upon ashaft'72 extending throu h theiwall IO-and" provided on its outer end swith'a handle i-73 i just the-conical end (35 into an l fl si d position," v.

and su pporting, the "outer endsof said ca sof commission or' any mixtureof oil,- steam;

and air may be provided-as desird:

By -providingv a device-(if: this kind in which thc'o'il is discharged into the-fire-pot through an annular passe 6 within thdfconfines of which isuperhetit heated compressed air are mixed. with said 1 the oil'is more thorou hly-atomizedand a greatly increased bone 1; is derived. By

steam and superproviding superheated compressed air and superheated steam ina dry state tobemixed with the; oil-'atits pointof; ignition fthisioil i l being also under ressure an intense heat is provided which is itself utilized to effect the superheating of the steam and compressed air which is being used.

By adjust-ingthe various tubular memhers relative to one another and thereby do I creasing the area of the outlet apertures the 1 amount of material which may pass through said. outlets is reduced and the material which does passlhrough is caused to pass therethrough at an increased pressure, thus insuring a greatly improved result.

It is believed that the operation of the invention will be fully understood from the foregoing description.
